MATTHIAS HOHNER, OF TROSSINGEN, GERMANY, ASSIGNOR TO HANS HOHNER, .OFNEW YORK, N. Y.

MOUTH-ACCORDION.

To all whom it may concern:

Be it known that I, MAT'rHIAs HOHNER, a citizen of Germany, residing atTrossingen, Germany, have invented new and useful Tmprovements inMouth-Accordions, of which the following is a specification.

This invention relates to a mouth accordion which is so constructed thatthe moisture carried by the air from the players mouth is not liable toreach and injuriously affect the reeds.

The invention also comprises various features of improvement by whichthe construc tion of the instrument is simplified and its tone enhanced.

In the accompanying drawing: Figure 1 is a plan of my improved mouthaccordion with the sound deflector partly broken away Fig. 2 a bottomView with the base plate removed; Fig. 3 a longitudinal section of themouth accordion on line 3*3, Fig. 1, and Fig. 1 a cross section on line4=4, Fig. 1.

The instrument is composed of a rectangular boX 10, between the bottomplate 11 and top plate 12 of which is formed a wind chest 13, into whichair is blown by the player through nozzle or mouth piece 14; entering anapertured side wall of the wind chest;

Opposite this nozzle there depends from top plate 12, a transverseabsorbent pad 15, which takes up the moisture carried by the air andchecks its flow into the instrument.

From the top plate 12 extend upwardly two rails 16, 17, of which rail 16constitutes a key-board and carries the keys for playing the air, whilerail 17 carries the base key levers. Along the inner side of rail 16,and thus flanked by rails 16, 17, are formed on top of plate 12, aseries of smaller cells 18, that project beneath rail 16 and communicatewith wind chest 13 by ducts 19 in plate 12. These ducts are controlledby the keys of disk valves 20, guided in tubular sleeves 21 of key-board16 and drawn normally against their seats by springs 22. Upon the walls23 of cells 18 is supported the usual reed-plate 24 having two reedsabove each cell, one of which is vibrated by pressure, while the otheris vibrated by suction.

Specification of Letters Patent.

Application filed February 18, 1908.

Patented July 28, 1908.

Serial No. 416,619.

It will be seen that by-the construction described only such reeds asare being sounded are placed in communication with the wind chest 13, sothat moisture is eflectively eX- cluded from all inactive reeds.Moreover, by the use of disk valves in lieu of the lever actuated valvesusually employed in this class of instruments, the construction of thelatter is greatly simplified.

The large cells 25 for the base notes, together with their reed plates26 are arranged within wind chest 13. The vibration of these reeds iscontrolled by flap-valves 27 pivoted to rail 17 and adapted to close thesound openings of said rail.

Both the rails 16 and 17 are grooved along their inner side for theaccommodation of a removable flanged sound deflector 28. This sounddeflector spans, the instrument between the rails above cells 18, andserves to concentrate and direct the tone. As shown in the drawing, thesound deflector is of semitubular shape, but itsiorm may obviously bevaried without departing from the spirit of the invention.

It will be seen that my improved mouth accordion is so constructed thatits durability is increased, its manipulation simplified, and greaterfullness of tone is insured.

I claim:

1. A mouth accordion provided .with a wind chest, an upper perforatedplate, cells above said plate, a reed plate above the cells, a pair ofrails flanking the cells, keys carried by one of said rails, and a sounddeflector engaging the rails, substantially as specified.

2. A mouth accordion having a wind chest, a nozzle entering the same,and an absorbent pad within the wind chest opposite the noz-.

zle, substantially as specified.
